Title: RC3 out of memory crash each night
Post by: tariqf on June 28, 2006, 10:21:23 AM

I have installed a new sme7 rc3 onto my amd 2600+ mobo with 512MB RAM and an 80GB hard disk. I have 5 users.

The server works fine all day but crashes each and every night and then needs power cycling each morning to get it going. If I look into /var/log/messeges I can see

...

this goes on until eventually the server freezes.

Please can anyone advise? Should I put more memory in? I thought 512MB would be enough for 5 users using email + domain logons.

I noticed that the swap size is only 300 odd meg. Is it me or does this seem low?
